When an unfortunate event affects the motor capacity of a person, it is
necessary to use devices like wheelchairs that offer a means o displacement
for patients with motors problems of the lower limbs.
Some patients that cannot manipulate the wheelchair with their arms due to a
lack of force or psychomotor problems in the superior members, request
electric wheelchairs, frequently manipulated with joysticks; however the
joystick manipulation is even not practical and frequently it must be handle
with the mouth.
The present article presents the partial results in the development of a
wheelchair controlled by an intuitive interface, where the instructions are
given by hand gesture instructions.
The advances are presented in the realization of the control software using a
Webcam and some distances and presence sensors controlled by a PIC
microcontroller that establishes the communication with a program developed in
Lab view .
